It is in the middle of 14.44. I couldn't do it on 9/23 because I came to work early in the morning. After returning home at night, I'm tired and unmotivated. I felt again that it would be better to do it in the morning.
It is in the middle of Exercise 14.3.2.3. I understand the meaning of INNER JOIN, but I've never seen it written in SQL statements. I think it's because the knowledge of the database is the same as before.
14.3 Done.
